Recovery of extra-heavy oil and minerals from carbonate

The strong interactions between asphalt and minerals make water-based extraction work poorly in separating this kind of ore. Herein, a reactive extraction process has been proposed to separate asphalt and mineral solids from the ores through dissolving the mineral solids (i.e., carbonate minerals, metal oxides, etc.) by acids

Separation of asphalt from carbonate ore surfaces by

Apr 28, 2020 Separation of asphalt from carbonate unconventional ores is a challenge due to the strong interactions between carbonate mineral surfaces and asphalt. Our previous results show that the reactive extraction process performs well in recovering both extra-heavy oil and minerals from carbonate oil ores (RSC Adv. 2019, 9: 14372–14381).

asphalt Components, Development, Properties, & Facts

Asphalt consists of compounds of hydrogen and carbon with minor proportions of nitrogen, sulfur, and oxygen. Natural asphalt (also called brea), which is believed to be formed during an early stage in the breakdown of organic marine deposits into petroleum, characteristically contains minerals, while residual petroleum asphalt does not.

What minerals are in asphalt? Answers

There aren't any minerals. I mean, there might be a faint little small bit of some minerals in it, but asphalt isn't made from minerals like a lot of other things.

Asphalt Extraction and Recovery Procedures

– The asphalt binder content is calculated by difference from the mass of extracted aggregate, moisture content, if determined, and mineral matter in the effluent (binder-solvent solution). The bitumen content is expressed as a mass percent of moisture-free mixtures.

Characterization of Recovery in Asphalt Binders

The recovery property of asphalt binders plays an important role in the performance and service life of asphalt pavements. Since the internal stress is the driving force for the recovery of asphalt binders, the accurate measurement of the internal stress is full of significance. Based on this rationale, this paper aims to measure the internal stress of asphalt binders using a creep and step

The nature of the Indonesian carbonate asphalt rocks and

The complex relationship between the oil and minerals (e.g., silica, calcite, illite) makes it much tougher for the heavy oil recovery. We evidenced that the Indonesian asphalt rocks are composed of porous foraminifera fossils with asphalt covering the whole porous particles (80–400 μm).

Recovery of Heavy Hydrocarbons from Indonesian Carbonate

Quite different from the Canadian oil sands in oil content/composition, mineral composition, and particle size distribution, the carbonate Indonesian asphalt rocks (oil-wetted) are proven to be poorly extracted by the commercial hot-water-based extraction (7.8% bitumen recovery at 50 °C and pH 9.0). Great enhancement was obtained using multi-staged solvent extraction with four typical
